What happened at 8:36am on 9/11/01?American Airlines Flight 11 and United Airlines Flight 175 were the two airplanes that hit the World Trade Center Towers, on September 11th, 2001. The 9/11 Commission Report published the flight paths of both airplanes. The flight paths originate from Boston, and cross paths once before their paths meet again in New York City.

Point A is the approximate location of the overlap. Point A is the location of New Windsor, New York. This also happens to be the location of the Stewart Air National Guard Base (aka Stewart Air Force Base, aka Stewart International Airport).

Not only did AA 11 and UA 175 both fly over New Windsor, NY, but they both flew over it at the same time, supposedly almost crashing into each other. This is an unlikely coincidence, since it would be far more likely that if the paths taken from Boston to New York crossed, that the planes would not cross paths at the same time. This occurred at approximately 8:36 am.

Directly From USA Today:The two hijacked jets that demolished the World Trade Center nearly crashed into each other while heading to their target, according to a Federal Aviation Administration employee at a regional control center. “The two aircraft got too close to each other down by Stewart” International Airport in New Windsor, N.Y., about 55 miles north of New York City, the employee told The Telegraph of Nashua.

At 8.37:08, UA 175 is asked to look for a lost American Airlines plane: “Do you have traffic look at uh your 12 to 1o’clock at about, uh, 10 miles southbound to see if you can see an American seventy six seven out there please.” UA 175 replies: “Affirmative we have him, uh, he looks, uh, about 20, yeah, about 29, 28,000.”

The map below, published by USA Today, shows the planes’ scheduled flight path and the actual route taken. This diagram also illustrates the strange path taken by AA 11 since when it deviated from its flight path, it headed away from New York City. Had AA 11 not taken the detour, the planes would not have crossed paths over New Windsor at the same time. Also note that UA 175’s scheduled flight path takes it directly over New Windsor and that it was not even supposedly hijacked until around the time AA 11 hit the North Tower. After UA 175 is hijacked, it does not fly directly to New York City. UA 175 hit the South Tower, 17 minutes later, leaving enough time for news crews to have their cameras set up, pointed up at the Twin Towers.

Amy Sweeney, a flight attendant on board AA 11, made a phone call(s) to American Airlines Flight service manager Michael Woodward. Sweeney first called at 8:22. At approximately 8:36, Sweeney reported that the plane began a rapid descent.

About 15 minutes after the women first called, the plane suddenly lurched, tilting all the way to one side, then becoming horizontal again. Ong said the plane was flying erratically, and Sweeney said it had begun a rapid descent. “For a flight attendant to say rapid descent, it’s rapid and it’s quick. We don’t use those terms very loosely,” said Woodward.

The transponder on AA 11 was turned off at 8:21 and as a result, the altitude of the plane from this time on, is never officially known.

This analysis of the flight paths suggests that it was necessary for AA 11 and UA 175 to both pass over Stewart AFB in New Windsor, NY at the same time. The reason why this was necessary is unclear. This occurred at approximately 8:36am.

At this same time, 8:36am, AA 77 (the flight that hit the pentagon) had deviated from its flight path and changed altitude. AA 77 was instructed by ATC to make two, 20 degree, turns and change altitude before returning to its scheduled flight path. This is routene procedure to aviod other aircrafts (traffic).

Routine radio communication was made with the pilot of AA 77 at 8:51. Shortly thereafter, the plane was suspected to have been hijacked since it made an unauthorized turn at 8:54 and then the transponder wass turned off at 8:56. Once the transponder was turned off, the flight path taken towards the Pentagon cannot be determined because ATC could not track the plane with primary surveillance radar (PSR). PSR operates totally independently of the target aircraft – that is, no action from the aircraft is required for it to provide a radar return. Since ATC could not track AA 77 with PSR like they had done with the other three hijacked planes when their transponders were turned off, ATC assumed it crashed. This reasonable assumption allowed AA 77 to hit the pentagon at 9:37 without being intercepted by the military.

The fact that AA 11 and UA 175 crossed paths at the same time is too improbable to be regarded as a coincidence, implying that this was necessary for the attack. Further research needs to be done on this topic to determine what happened to AA 11 and UA 175 over Stewart AFB in New Windsor, N.Y. at 8:36am when AA 11 began a rapid decent.
